Case Study: Leading Japanese ISP BIGLOBE achieves lower-cost, high-density, petabyte-scale mail storage for 3 million users with Hewlett Packard Enterprise ProLiant SL4500

BIGLOBE Constructs Lower Cost, High Density Scalable Storage Environment

BIGLOBE, a leading Japanese ISP and cloud services provider, needed a more robust, scalable and lower‑cost mail storage system to support rapidly growing mail data for its broadband users (the case references 3 million users and more than 500 TB of data). To meet these demands the customer selected Hewlett Packard Enterprise hardware—specifically the HPE ProLiant SL4540 Gen8 servers in the HPE ProLiant SL4500 scalable system—and HPE Support Plus 24 alongside object storage software to replace legacy NAS/SAN approaches.

Hewlett Packard Enterprise supplied ultra‑high‑density HPE ProLiant SL4540 Gen8 nodes running Scality RING, initially deployed as a 6‑node (3 chassis) system with 88 TB and 192 GB RAM per node and planned to scale to 26 nodes (~2+ PB). The solution delivered petabyte‑class, scale‑out object storage with seamless Zimbra integration, cut total storage costs by about two‑thirds (operating at roughly one‑third of prior cost), reduced O&M overhead through self‑management features, and provided 24/7 on‑site support and rapid maintenance via HPE Support Plus 24.
